Cheating System Novels & Stories

Even after a full decade of marriage, my husband Rudolf and I were as deeply in love as the day we wed—an enviable couple in the eyes of all. On the day of our anniversary, I saw him lifting a little boy into his arms right outside the entrance of our neighborhood. "Daddy! Can you take me to the amusement park this time?" The boy's words were enough to stop me dead in my tracks. I instinctively hid around a corner. "Of course! I'll even take you on a trip." Rudolf smiled warmly and kissed the boy on the forehead. In that instant, something seemed to have been set off in my head, as if years of trust had been shattered at that one moment. Daddy? Upon closer examination, I realized that the boy's features were remarkably similar to Rudolf's. No one could deny they were blood-related. "Your dad's busy with work, sweetheart. Don't cling to him too much," said a beautiful woman standing next to the boy. The cruel moment before me made it clear. The man who swore he would love me forever had been cheating all along.

I had agreed to pay 10,000 at the wedding. At the very last minute, my mother-in-law, Alice Thompson, suddenly raised it to 500,000. I went to confront them. My husband, Dylan Forrest, kept his head down, pretending not to hear a thing as he looked at his phone. Alice rolled her eyes, clearly about to brush me off with some excuse. But instead, the truth spilled out of her mouth against her will. "Of course we have to take advantage of you being pregnant and unable to run to squeeze as much money as we can. It's the perfect timing to use it to buy Gideon a house, paid in full!" The words were like a silent explosion. I was so furious I actually laughed. "So, that's the plan? You're trying to strip me for everything I have? If I don't pay, does that mean there's no wedding?" Alice clamped a hand over her mouth, panic flashing across her face. But her voice came out louder than ever, like it was blasting through a speaker. "If you don't pay, then get lost! You're just a pregnant, used woman. Who else would want you besides Dylan?" The guests erupted instantly. Dylan's face went pale as paper. I smiled. Then a mechanical voice rang in my head. "Honest Lies System activated. Malicious fraud detected. Reward granted: 100 billion. Match assigned: the richest man in Lumeria at the next table." "Fine," I said softly. "You said it yourself." I wanted to see just how the Forrests planned to show their faces tomorrow after every ugly truth they'd tried to hide was dragged out into the open.

At my wedding, a video of my fiancé cheating was exposed. I didn't make a scene; just turned around and walked away, left him to clean up the mess himself. I went back to my room and kissed my younger boyfriend. We were halfway through when we got interrupted. My fiancé stormed in, face red with shame and rage. "Is this really the time? All you can think about is kissing?" I smacked my lips, still savoring the moment. "Weren't you the one who introduced us?"

Kieran Voss is my boyfriend, and his first love has slept with every one of his closest friends. Yet, she still manages to play the innocent little angel in front of him. I plan to expose her, especially after I accidentally uncover her biggest secret. But before I can, Chloe Bennett uses dark magic and somehow transfers all her physical reactions onto me. She's flirting with a man below the stage while I'm giving a company presentation. I can't help but let out a soft moan at the podium the moment his hand slips under her skirt. I become the shameless and indecent woman everyone despises. Despite this, my boyfriend goes against public opinion and proposes to me in front of everyone. Chloe spends ten hours in bed with ten men on our wedding day. Meanwhile, I collapse on stage and tremble uncontrollably in a white gown, my face burning red with heat. I die of heart failure from sheer excitement and carry a tarnished name even in death. As I open my eyes, I'm back to the moment I first discovered Chloe's secret. This time, I close my eyes and say "Don't worry, I swear I didn't see a thing."

To stop my boyfriend from marrying me, his mother hired a group of thugs to kidnap me. They dragged me into the woods and tortured me for an entire day and night, leaving barely a patch of uninjured skin on my body. Eden York lost his mind after finding me. He went after every single person involved and ruined them without hesitation, even personally sending his own mother to prison. He never once cared about what had happened to me. If anything, he became even more determined to marry me, willing to turn his back on his entire family to make it happen. But the moment I woke up in the hospital again, a cold mechanical voice suddenly echoed in my head. [Host, your target’s affection level has reached 100%. Final marriage mission unlocked.] [Complete the mission to receive a sixty-million-dollar reward. You may also choose whether to leave this world.] [Warning: If the mission fails, you will be permanently erased from this world.] I was still trying to process the words when Eden’s voice suddenly rang out in my mind. [Perfect. After everything I did with my mother to set this up, I finally maxed out her affection points.] [Once the final mission is complete, I’ll dump her immediately and be with Tiffany instead.] Beside me, Eden instantly noticed how pale I had gone and reached out to touch my face. “Summer, what’s wrong? Are you feeling sick?” I slowly shook my head. “No. I’m just really looking forward to the wedding in seven days.”

After I was caught in a dockside explosion, I was bound to a Survival Program. It gave me twenty-five years and four designated targets. If even one target’s Love Score or bond score reached 100%, I could wake up in my real world. But I failed all four. Because every target I tried to reach eventually turned toward Sophia Lane, the heroine of this world. They called my pain a performance. They called my tears manipulation. They said I was only pretending to break down so they would choose me over Sophia. But if they never loved me, why did they lose control when my mission failed and I chose to leave this world for good?

They buried him under a blood-red moon. Chains of silver and blessed iron pinned his broken body to the earth, sealing his power, erasing his name. To the pack, he was a failed Alpha. To the coven, a cursed vampire. To the world, he was a mistake that deserved to die. But monsters don’t stay dead. When Alpha opened his eyes again, he wasn’t in the grave—he was in the body of his weakest self. Eighteen years old. Rankless. Powerless. His wolf silent. His vampire blood thin and starving. The memories of his execution burned behind his eyes like fresh wounds. Reborn. A second life… and a second chance at vengeance. This time, he felt it—the system etched into his soul, ancient and cruel. [Hybrid Core Detected] Bloodline: Vampire / Werewolf / Unknown Status: Severely Suppressed Level: 1

It's my and my boyfriend's anniversary. I open the glovebox to hide a gift inside as a surprise, but a piece of familiar-looking lingerie falls out. It's torn in a spot; it looks like it went through a rough battle. Before I can process the situation, I crash into a car that suddenly switches lanes in front of me. Right before I black out, I remember where I saw the lingerie. It was a gift from me to my best friend.

My boyfriend, Allen, is a fitness coach who is cheerful, handsome, and has eight-pack abs. After getting together with me, he transferred all his female students to other colleagues and would send me daily check-in photos. In anticipation of becoming his fiancee, I happily prepared for our engagement ceremony. However, two weeks before the ceremony, I discovered a bright red lipstick mark on Allen’s workout pants. I quickly pulled up the check-in photo he had sent me that day. Through the reflection on a dumbbell, I saw a woman standing next to Allen—her lips painted in the exact same lipstick color. Most of the previous photos had flaws, but I had trusted Allen too much to notice them. Looking at his message under the photo, I let out a cold laugh. "Baby, I have to work overtime today to train a male student." He actually dared to deceive me. Just then, my phone rang. It was the wedding planning company confirming the engagement ceremony setup. I quickly responded with a confirmation. The ceremony would proceed as planned—except I had a special surprise prepared for Allen, one he would never forget.

After my rebirth, the very first thing I did was ride from one blood donation van to another, giving blood until I nearly collapsed. Why? Because in my previous life, my fiancé's newly hired intern, Shirley Lynch, had bound herself to a blood-exchange system. Every milliliter she donated was siphoned directly from my own veins. In just a month, she transformed from an ordinary college girl into the nation's beloved Blood Angel, showered with fame and fortune, while I, suffering from severe anemia, was fired from the hospital for being unable to work. When I exposed her scheme to my fiancé, he looked at me with disgust and broke off our engagement. "You're selfish and cowardly," he sneered. "You refuse to donate your rare blood type, and now you slander Shirley? You call yourself a doctor, yet you believe in such ridiculous nonsense!" From then on, every time Shirley donated blood, I would suffer heart palpitations, dizziness, and sometimes collapse outright. I begged the doctors in my department for help, but my fiancé blocked every attempt, accusing me of jealousy and wasting medical resources. In the end, to steal my promotion ahead of schedule, Shirley donated a full 1000 milliliters of blood live on television. As her blood drained, so did mine. I went into shock and died. When I opened my eyes again, I was back on the very day Shirley first claimed she carried my rare blood type.
